LOADING-MACHINE Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed May 8,1919. Serial No. 295,609.

To (1:25 whom it may concern:

Be it known that I, Nonron A. NEWDICK, a citizen ol the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Loading-Machines, ofwhich the following is a specification.

This invention relates to loading machines adapted to gather and loadmaterials of many kinds but the particular embodiment of the inventionherein shown and described being more particularly intended to load coalin the mine into the mine cars.

A primary object of the invention is to provide a single unitloadingmachine of the character above indicated, constructed in such mannerthat the discharge end of the gatheringconveyer may be maintained inoperative position with respect to the mine car, even thou h the truckof the loading machine and t e mine car may be located upon a sharpcurve. In machines of this character it is necessary to providesufficient overhang of the gathering conveyer at the rear of itssupporting truck to permit the mine car to be manipulated therebeneathto distribute the load evenly within the mine car. It is apparent thatwith sufficient overhang to permit the manipulation of a mine car ofeven moderate length beneath the discharge end of the conveyer, suchdischarge end will, if the curvature of the track is such as to causethe truck and the mine car to lie at an angle with respect to eachother, tend to move laterally beyond the track and consequently beyondthe mine car;

The present invention contemplates the provision of a single unitloading machine in which means are provided for permitting the supportupon which the gathering conveyer is pivotally supported from its truck,to be shifted bodily laterally to compensate for the tendency of thedischarge end of the gathering conveyer to move laterally beyond themine car under the conditions set forth, whereby such discharge end willbe maintained in a position to discharge into the mine car, irrespectiveof how sharp the curve mgy be upon which the work is being done.

11 the accompanying drawings, WhlCll are 'merely illustrative of theprinciples constituting'the inventive thought,

Figure 1 is aside elevation of a loading machine constructed inaccordance with the ing wheels for said truck, these wheels beingpreferably, though not necessarily, flanged to engage the track uponwhich the mine car 7 travels. At 8 I have diagrammatically illustrated amotor which through pinion 9 and gear 10 is adapted to impart movementto the wheels 6. If desired, sprockets 11 and 12 mounted upon the axlesof the truck may be connected by a sprocket chain 13 to cause all ofsaid wheels to be driven from the motor 8. Trunnioned at 14' in theframe of the truck is a saddle casting 15. extension 16 of this castingis provided with tongues 17 and 18 which enter corresponding grooves 19and 20 formed in the saddle oasting to adapt the rearward extension 16to have a bodily transverse movement upon the saddle casting 15. Inorder to impart such bodily movement to the extension 16 said extensionis provided with a threaded lug 21 which constitutes a nut and whichengages a screw 22. A sprocket 23 upon the end of this screw isconnected by a chain 24 with a sprocket 25 upon the shaft of a motor 26.It is apparent that if this motor, which is preferably an electricmotor, be energized, rotation will be imparted to the screw 22 and thatthis will in turn impart bodily lateral movement to the extension 16.

A gathering conveyer 27 is pivotally mounted at 28 in the rear end ofthe extension 16 and swings about the axis constituted by said pivot sothat it may sweep back and forth in a substantially horizontal planeacross a mine floor, it being understood that in the drawing thisconveyer is merely diagrammatically illustrated, being of a well knowntype, such, for example, as illustrated in my co-pending application,Serial No. 96,723, filed May 10, 1916.

This type of gathering conveyer comprises a pan 29 divided by a centralhousing 30 into slideways 31 and 32 in which the flights 33 travel, itbeing understoodthat these flights are adapted to travel in eitherdirection and that the conveyer is adapted to A rearward gather coalwhen swung in either direction. The flights 33 are carried by chainsindicated at 3st to which motion is imparted from a motor Clips 36 uponthe top of the extension 16 engage over an arcuate ring 37 carried bythe underside of the pan 29, these clips being disposed upon the of acircle struck from th center of the pivot 28. It will thus be seen thatas the conveyer swings back and forth it will gather coal or othermaterial and discharge it from the rear end of said cenveyer into themine car 7 and that it the truck of the gathering conveyor and the minecar move to sharply angular positions when working about curves in themines, the conveyer may be shifted bodily laterally with respect to itssupporting truck to keep its discharge end over the mine car.

It is to be noted that the support of the saddle casting is between theaxles of the truck so that the weight of the conveyor and of the coalbeing loaded is equally dis tributed upon the driving wheels of thetruck. Furthermore, this aids in counterbalancing the weight upon thegathering end of the conveyer and relieves friction between the nose ofthe conveyer and the mine floor.

It is to be understood that the invention is not limited to the preciseconstruction set forth but that it includes within its purview anychanges coming within the terms or the spirit of the appended claims.

Having described my invention, what I claim is:

1. In a loading machine, a supporting truck, a saddle casting trunnionedthereon about a horizontal axis, a member slidably mounted upon thesaddle casting to move sidewise, means for imparting movement to saidmember and a gathering conveyer mounted upon said member.

2. In a loading machine, a supporting truck, a saddle casting trunnionedthereon about a horizontal axis, a member slidably mounted upon thesaddle casting to move sidewise, means for imparting movement to saidmember and a gathering conveyer pivotally mounted upon said member toswing about a vertical axis.

3. In a machine of the character described, the combination with asupporting truck, an element trunnioned about a horizontal axis uponsaid truck, a second element slidably mounted for sidewisc movement uponthe first named element, and a gathering conveyer pivoted upon thesecond element.

1-. In a loading machine, the combination with a supporting trurlt, oil.an element mounted thereon, a second element slidably mounted upon thefirst named clement a, screw carried by one of said elements andengaging the other for imparting sidewise movement to the second elementwith respect to the first element, means for operating said screw and agathering conveyer pivoted upon the second element to swing about avertical axis.

5. In a loading machine, the combination with a supporting truck, oil anelement mounted thereon between the axles of the truck, a rearwart'lextension slidably mounted upon said element to move sidewise, means forimparting movement to said rearward extension and a conveyer supportedupon said extension.

(3. In a, loading machine, the combination with a supporting truck, ofan element mounted thereon between the axles of the truck, a rearwardextension slidably mounted upon said element to move sidewise, means forimparting movement to said rearward extension and a conveyor pivotedupon said extension to swing about a vertical axis.

In testimony whereof I atlix my signature.
